Engine pump aggregate
t  is a complete component consisting of the steering hydraulics pump -V119- (electric motor and gear rack pump), the power-steering control unit -J500- and the hydraulic oil reservoir.
t  has a re-engaging protection after faults, failure or crash → Chapter
  Note
t  Repairs on the pump -V119- and -J500- are not foreseen.
t  The cause of any problems which may be arising is determined by the pressure and tightness test.
t  If there is insufficient hydraulic oil in the reservoir always check the steering system for tightness.
t  If there is a leak in the area of the line connection first check the lines/line connections for tightness, if necessary retighten and wipe dry.
t  Do not use drained hydraulic oil again.
t  Always replace gasket rings.
